Reliability, versatility, and value make the Model 2000 the ideal semi-auto shotgun. Inside the Stoeger Model 2000 semi-auto shotgun is the Inertia Driven operating system, the heart of the world's most prestigious and reliable autoloaders. The Inertia Driven system has only three moving parts in the bolt, the inertia spring, the bolt body, and the rotating locking head, for more reliable operation. The operating system is mostly contained in the receiver, giving the Model 2000 a trimmer forend with better balance. The Stoeger Model 2000 fires everything from 1-1/8 ounce field and target loads to the heaviest 3" waterfowl loads without adjustments. Plus, with no propellant gas venting into the operating system, the Model 2000 stays cleaner. The bolt assembly includes an inertia spring and a rotating locking head and a cavity is designed into the butt stock of the Model 2000 to allow installation of an optional, mercury-filled recoil reducer. A red bar front sight helps you pick up the target even in low-light hunting situations. Five choke tubes ranging from cylinder to extra-full turkey come standard.
